Implementation of a technique for the use of Tarwi alkaloids and subsequent complexion of heavy metals
Abstract
The appropriate conditions to form complexes with Tarwi debittering alkaloids and heavy metals present in wastewater are determined. For this purpose, standard solutions of heavy metals and Tarwi debittering waters with different alkaloid concentrations were used, in addition to volumetric, potentiometric and spectrophotometric techniques for data collection and construct multifactorial experimental designs, for Cadmium, Lead and Chromium. used in the present study. The results obtained indicate that at a concentration of 4.59 mg/ml of alkaloid and at pH 4 Cadmium precipitates; at a concentration of 1.24 mg/ml of alkaloid and at a pH between 3 and 4.5 Lead precipitates; and at a concentration of 4.59 mg/ml of alkaloid and at pH 8 Chromium precipitates, reducing the levels of Chromium, Cadmium and Lead by 76, 85 and 91% respectively. The conditions obtained are applied to a sample of petroleum formation water, reducing Lead by 17%, demonstrating that the alkaloids precipitate heavy metals, in addition to the fact that there are interferences that hinder the treatment of metals in the formation water sample.
